2024-07-05 Deformation-induced phase separation of active vesicles doi:10.57760/sciencedb.09562 en Many active materials, such as bacteria and cells, are deformable. Deformability significantly affects their collective behaviors and movements in complex environments. Here, we introduce a two-dimensional deformable active vesicle (DAV) model to emulate cell-like deformable active matter, wherein the deformability can be continuously adjusted. We find that changes in deformability can induce phase separation of DAVs. The system can transition between a homogeneous gas state, a coexistence of gas and liquid, and a coexistence of gas and solid. The occurrence of deformation-induced phase separation is accompanied by nonmonotonic changes in effective concentration, particle size and shape. Moreover, the degree of deformability also impacts the motility and stress within the dense phase following phase separation. Our results offer new insights into the role of deformability in the collective behavior of active matter.  active vesicles; formable degeneration; self-assembly; porous barrier array Yi-yang Jin Yan Jin Zi-xuan Shi Kang Chen Wen-de Tian Tian-hui Zhang PUBLIC https://opendatacommons.org/licenses/by/1-0/ dataset Science Data Bank
